Abstract
Medical devices that are coated with an echogenic material that includes an electrically insulative base layer and an echogenic layer demonstrate both improved ultrasonic imaging and protection against RF electrical breakdown. The echogenic layer includes a polymeric matrix that (i) defines a plurality of void spaces, (ii) includes glass microsphere particles, or (iii) both defines a plurality of void spaces and includes glass microsphere particles. Medical instruments exhibit enhanced ultrasonic imaging even when viewed along their lengths.
